The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

We discover in this paper that when environmental noise is strongly dependent on the population size, this noise may suppress the population explosion in a finite time and guarantee the global positive solution. When the environmental noise is weakly dependent on the population size, the conditions that guarantee the global positive solution are independent of this environmental noise. We also discuss the pth moment boundedness, stochastic ultimate boundedness, and moment average boundedness in time under two classes of conditions. These properties are natural requirements from the biological point of view.
